Open design with adapter ring
The adapter ring allows adaptation to different
connection dimensions. A seal is required on the
motor output shaft.
The adapter ring (5) and drive hub (1) are
delivered loose. Clean the fitting surfaces of the
motor (3) and drive hub. Check the motor shaft (2)
for axial and radial runout as described in chapter
3.1. Also lightly grease the motor shaft.
After cleaning the fitting surfaces, place the
adapter ring onto the motor housing. Then heat
the drive hub to approx. 120 °C from the opening
and slide it onto the motor shaft (2) until it reaches
the stop or shim (13).
CAUTION
Risk of motor shaft damage if the hub is not
sufficiently heated.
Tighten the threaded pin (9) and secure it to
prevent it from turning, see chap. 3.4.
